Abstract: In accordance with the preferred embodiment, an access point provides dynamic load balancing of network bandwidth between access points within the 802.11 wireless LAN. The access point uses the RTS/CTS protocol to reduce the bandwidth available to a single device using an excessive amount of network bandwidth. The access point places a device that has been monopolizing a network channel on a Restricted List, and regulates bandwidth on the network by not returning a CTS to any client on the Restricted List. When the client's network usage drops below a policy driven threshold set by the number of network users, the client is removed from the list and the access point will respond to a RTS from the client with a CTS.

Abstract: A data processing system and method are described for permitting a server computer system to remotely access asset information stored within one of a plurality of client computer systems. The client computer systems are coupled to the server computer system utilizing a network. Asset information is stored in a storage device within the particular client computer system. The asset information includes information identifying a plurality of components of the client computer system. The server computer system transmits a message to the client computer system while the client computer system is powered-off. A network adapter is included within the client computer system. The network adapter accesses the storage device to obtain the asset information while the client computer system is powered-off.

Abstract: A system for monitoring tamper events in a computer system 10 is disclosed. The computer system is on a network. The system comprises a tamper realtime clock (RTC) means 140 which receives at least one tamper event signal from the computer system. The tamper RTC includes a timer 178 for indicating the time of a tamper event and a management device 160 for receiving the at least one tamper event signal. The management device issues a command to the tamper RTC means to obtain the time of the at least one tamper event. The management device also generates a network packet 200 which includes the time of the tamper event to a system administrator of the network. Preferably the computer system has the ability to functionally detect and store the time of a tamper event. A tamper real time clock (RTC) circuit is operatively connected with logic to store the date and time of an event as it occurs. In a preferred embodiment, the tamper event could be as simple as a toggle switch being activated when a cover on the computer system is removed. The computer system also sends network alerts when the cover is removed.

Abstract: A data processing system and method are described for permitting a server computer system to remotely disable an ability of a client computer system to access a network which couples the client computer system to the server computer system. The server computer system transmits an indication to the client computer system utilizing the network that the ability of the client computer system to access said network be at least temporarily disabled. In response to a receipt of the indication by the client computer system, the ability of the client computer system to access the network is at least temporarily disabled. The client computer system is unable to transmit information utilizing the network while the client computer system is temporarily disabled.

Abstract: Method and system aspects for securely transferring a computer system are described. A computer system is disabled at a shipping point via an RFID (radio frequency identification) interface and re-enabled at a receiving point via the RFID interface. Disabling the computer system includes selecting a boot password, writing the boot password to storage in the computer system via the RFID interface, and setting a disable bit in the storage via the, RFID interface. Re-enabling the computer system includes entering the boot password via the RFID interface and clearing the disable bit.
